t1300: remove unreasonable expectation from TODO

In https://public-inbox.org/git/7vvc8alzat.fsf@alter.siamese.dyndns.org/
a reasonable patch was made quite a bit less so by changing a test case
demonstrating a bug to a test case that demonstrates that we ask for too
much: the test case 'unsetting the last key in a section removes header'
now expects a future bug fix to be able to determine whether a free-form
comment above a section header refers to said section or not.

Rather than shooting for the stars (and not even getting off the
ground), let's start shooting for something obtainable and be reasonably
confident that we *can* get it.
